人对振动主观反应的模糊随机评价模型

人对振动环境的主观反应有明显的模糊性和随机性，按照简单二值方式给出的烦恼阈限不能反映这个特点，从而导致了基于振动舒适度的可靠度计算结果的不确定性。本从心理物理学的角度对这些不确定性进行了分析，结合人对振动主观反应调查表的形式和有关实验数据，给出了相应的模糊隶属度和条件概率分布形式，从而建立了人对振动主观反应的模糊随机评价模型，同时给出了基于振动舒适度的失效概率的计算方法。

A Fuzzy-stochastic Model for Human Response to Vibrations

The annoyance threshold acceleration determined by the two-valued logic methodcan not describe the ambiguity and randomness existed in human response to vibra tion environments, which results in many uncertainties in the vibration comfort -based reliability analysis. All these uncertainties were analyzed from a viewp oint of psychophysics. The membership function and corresponding conditional pro bability distribution were determined based on the format of field survey tableand laboratory findings. At last, a fuzzy-stochastic model for human response t o vibrations was presented and through which the estimation method of failure pr obability in the comfort-based reliabolity analysis was given.
